We have a DRW, a 33' fifth wheel, and a " chase car".
The inconvenience of having to drive through and try to park in little coastal towns, not being able to get into certain places, having to park far away from certain attractions, and the amount of fuel we were using, led us to start our calculations.
Truck... 12- 15mpg ( not towing ) vs car... 35-42mpg... Convenience... Priceless.
Our little Sonic had 32k miles on her when we got her, has a bumper to bumper 100k warranty.
Our calculations for having the car...: Including purchase price, registration, insurance, fuel, and maintenance make it a perfect wash. Mind you, this also includes the Stanadyne in the truck, less maintenance on the truck, etc. Also, it will keep the resale value of our very low mileage truck at the top end. That alone, will pay for the purchase price of the car.
We arent going to get a tow set up for the car because it won't pay for itself by the time we go to trade in in.
We keep in touch via UHF radios.
DH drives the truck and fifth wheel, and I drive the car. I usually stay behind him, and advise him of any trouble coming from the back, and do traffic breaks for him.. and visa versa. When we get near our RV Park, or stopping place for the night, I go ahead of him and check in. He has me go check out the sites, if we have a choice of sites, and it gives me the ability to keep our 55 foot rig out of any trouble ( turning around, low branches, etc. )
We have had this set up traveling through 8 States, and have never had to pay extra for the car, and that includes quite a few State Parks.
We usually only have to stabilize the fifth wheel and take a little weight off the truck when we park. We don't have to do a full blown disconnect, which also gives the appearance that we are in our rig, and it's not sitting empty inviting any troubles.
Obviously, the set up we have doesn't work for everyone, but we are ecstatic with our set up.
Feel free to PM me if you are interested in our financial breakdown spreadsheet.
